Notes: Yes, it looks a lot like C. fimbriata, BUT, it is rather coarsely sorediate and some of the podetial stalks appear to be squamulose, and quite high up too, indicating that the podetial surface is corticate, which should not be the case in C. fimbriata. I wouldn't be positive without examining the material (and indeed if then), but on balance I think this is C. chlorophaea (agg.).
